SPECIFICATION forming part Of Letters Patent N 0. 649,940, dated May 22,1900. Application filed March 10, 1898. Renewed October 16, 1899. SerialNo. 73 8,825. (No model.)

To (tZZ whom it may concern.-

Be it known that I, GEORGE A. Lore, of Antwerp, in the county ofPaulding and State of Ohio, have invented certain new and use fulImprovements in Grain-Separators; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form part of thisspeciiication.

This invention relates to grain-separators, and has forits object toprovide improved machinery of this class for separating cockle and otherrefuse from the grain and for separatingthe various kinds of grain fromeach other or different grades of the same grain.

\Vith this object in view the invention consists in the improvedconstruction, arrangement, and combination of parts hereinafter fullydescribed and afterward specifically pointed out in the claims.

In the accompanying drawings, Figure 1 represents a view in elevation ofthat side of the machine upon which the fly-wheel is mounted. Fig. 2represents a view of the opposite side. Fig. 3 is a verticallongitudinal sectional view of the machine. Fig. l is a view in endelevation with a portion of the casing removed. Fig. 5 is a plan viewshowing the trough, table, and spiral conveyer. Fig. 6 is a longitudinalvertical sectional view throughthe trough and conveyor. Fig. 7 is a viewof one-half of a separating-cylinder with pockets approximating in shapea grain of wheat. Fig. 8 is a fragmentary view of part ofthe same inperspective section. Fig. 9 is a similar view of part of a cylinderhaving pockets tapered on one side and straight on the other. Fig. 10 isa view similar to Fig. 7, showing half a cylinder, with pocketsapproximating in shape a grain of rye. Fig. 11 is a view of part of acylinder having pockets approximating the shape of grains of oats. Fig.12 is an enlarged longitudinal vertical section through part of theupper surface of one of the perforated cylinders. Fig. 13 is a view inside elevation of one of the brushes. Fig. it is a perspective view ofone of the rings for securing the two halves of a cylinder together andwhich also serve as beltpulleys for rotating the cylinders.

Like letters of reference mark the same parts in all the figures of thedrawings.

Referring to the drawings, A marks the casing, which is shown asrectangular in shape, but which may be of other shape, if de-- sired. Inthe sides of the casingA are a series of openings through which toinsert the cylin' ders endwise, doors 0, O, and 0 being fitted to saidopenings. The openings, cylinders, and doors are arranged in series indifferent vertical and horizontal planes in such manner that the bottomof the upper cylinder is above the center of the next lower cylinder andso on to the lowest cylinder, so that the grain will pass from the lowerend of one cylinder into the next cylinder just below its center,passing in at a, at one end of the highest cylinder B, out of thatcylinder at a, atits lower end, into chutes or pipes b, suitably securedin openings at in the doors 0, O, and 0 bein g conveyed therethroughfrom one cylinder to the next until discharged at the lower end of thelowest cylinder, the inlet-point of each cylinder being marked a and thedischargepoint a.

The cylinders B B are made in sections, as shown in Figs. 7 and 10, themain body and edge flanges being made of a single piece of sheet metalfor each section, such sheet metal being formed with pockets, as shownat d in Figs. 3, S, 9, and 11, and such pockets made of approximatelythe shape of the grain to be lodged or retained in them, beingpreferably formed by punching outward with a suitable tool and forming aperforation with side walls or burs without the removal of any of themetal. The perforations are also shown at ff in Figs. 7 and 10, those inFig. 7 being intended to receive grains of wheat and those in Fig. 10grains of rye, while those of Fig. 11 are intended to receive grains ofcats.

The cylinders may be made with pockets, as indicated in Fig. 7, in whichthe pockets are simply depressions of the desired shape, no hole beingmade through the material of the cylinder, as in Figs. 10 and 11.

The cylinders are arranged to be made removable and interchangeable, sothat any one can be taken out of the machine and another to receiveanother kind or size of grain substituted for it when desired.

The sections of each cylinder are clamped together by means of rings D,which hold them securely-togetl1er,and are provided with externalcircumferential grooves to receive belts by which the. cylinders arerotated, the rings being secured by screws 9 or any other suitablefastening. The ends it of the cylinders form their journals, and theyhave their bearings in circular recesses t', formed in the doors 0 0' CWhen it is desired to remove acylin'de'r' from the machine, the doorsare taken off and the cylinder pulled out lengthwise, and when acylinder for a difierent grain is required the rings D are taken off,the sections of the cylinder removed from the machine and secured on theone to be substituted, which may then be placed in position inthe-machine.

The doors are substantially alike, being square in outline, the recesses'5, before mentioned, being formed in their inner faces, and in the doorbelow its center is a hole 70, in which j ournal-boxes Z are placed, inwhich are supported a central trough E and table F, the outer ends ofthe trough forming bearings for the journals of a spiral or screwconveyer G. (See Figs. 5 and 6.) The table F is formed of two leaves itand 0, secured to and projecting laterally from the trough E, one oneach side, extending the whole length of the trough,

one leaf reaching close enough to the side of the cylinder to preventthe passage downward of grain and the other at a sufficient distancefrom the opposite side of the cylinder to permit the passage upward ofthe grain lodged in the pockets without interference. The leaves inclinedownwardly and inwardly toward the trough, so that grain dropped out ofthe pockets on the upper inner side of the cylinder will slide down theleaves into the trough to be carried to the discharge end by theconveyer. The neck of the trough at the discharge end projects beyondthe door and is provided in its under side with an opening through whichthe grain is discharged into the chutes.-

The spiral conveyers G are rotated by belt on pulleys g from a suitabledriven pulley.

Over the cylinders B B are mounted brushes 1", extending the full lengthof the cylinders, said brushes being mounted in vertical grooves withtheir bristles bearing on the outside of the cylinders at the top andserving to force inward anything lodged in the punched-out pockets,causing it to drop inward upon the table F and leaving the pockets clearto take up other grain, &c.

The pockets in cylinder B being not ex'- tended through the shell of thecylinder, a longitudinal rotary brush K is mounted inside of it, so asto contact with its interior as the cylinder and brush rotate, thebristles of this brush being arranged spirally to feed the matter whichit removes from the pockets longitudinally of the cylinder to dischargeit at the end thereof, whence this matter is con- "eyed to the next orsucceeding cylinder and again submitted to the operation of separatingto further clear it of refuse, &c., or to remove from it good grainwhich may remain.

The middlecylinder B is provided on its outside with projections s s,which as the cylinder revolves pass under and raise a spring H, whichdrops off one projection and strikes the next or the shell of thecylinder, which so jars the cylinder as to cause the grain to surelydrop out of the inverted pockets upon the tableF to behandled by theconveyer G.

The various cylinders and conveyers are rotated in the proper directionsby suitable belts and pulleys, to which I make no claim,

being of any well-known style or arrange-' ment.

The operation is as follows: The grain is put in hopper L, Fig. 2, andpasses at a into and through the conduit or chute b to the inside ofcylinder 0, then into the separator above described, to the opposite endof the cylinder, to the discharge, one kind of grain passing out at thebottom of the cylinder, while the other grain or foreign matter passesout of the conveyer, as shown at 19, Figs. 4 and 6. When the grainenters middle cylinder E the operation is reversed. In all instances thegrain enters one end of the cylinder and discharges at the other end,the grain being conveyed through suitable conduits. Much dust and dirtscreens through the perforated cylinder to the inclined bottom f, fromwhich it is carried off. Parts of the casing or frame may be in sectionsand hinged, as at 'Lt M, for easy access, and the doors 0 C (3 may be secured by any well-known fastening, as at 'U '0. The doors should fittheir openings very snugly, but not too tightly,'as they may have to beremoved very frequently for the re moval and insertion of diflerentcylinders. Any usual and well-known motive power may be employed. Inthis instance only a hand wheel is shown, as seen at w.

Modifications and changes of the arrangement of the several parts may bemade within the scope and spirit of my invention, and I do not thereforewish to be confined to the exact forms shown and described, but considermyself entitled to all such modifica tions.

Having described my invention and illustrated the best means of carryingthe same into effect, what I claim as new, and desire to secure byLetters Patent, is-

1. The combination in a grain-separator of the casing having openings,doors fitted in said openings and having circular recesses in theirinner faces of the size of the cylinder ends, and the cylinder endsadapted to form journals and mounted and supported in the recesses inthe doors which form the bearings therefor, substantially as set forth.

2. The combination in a grain-separator of the cylinders made insections of halves, a

driving pulley-ring securing said sections together, the end of saidcylinders forming journals and adapted to operate in journa1-bear ingsformed by recesses in the doors, Where- I by when the doors are removedthe cylinders are accessible substantially as set forth.

3. The combination in a grain-separator of the doors recessed asdescribed, the cylinders having ends forming journals to fit said re- 10cesses, conveyers in said cylinders, and the conduits or chutes carriedby said doors for communication between the cylinders as set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of 15' two Witnesses.
